Always wanted a smoke trail from my plane....

[Captainchris]

Turned up nice and early on a sunny morning, put the plane together, and did all the usual checks and everything was working perfect.

Put the throttle up, and she took of in to the sunrise PERFECT.

Did a few laps, trimming it out when the engine cut out, I immediately thought my battery was running low on the transmitter but then the engine started again.

Then I started to see a smoke trail....... and not in a good way, had all other controls just no power, thankfully I was high so I glided it in, smoke trailing behind,... Felt like a 109 had shot me out of the sky!

Did a perfect landing (even under the stress I was under, i was well chuffed) ran to the plane, and didn't know what to do....
Smoke was everywhere, so I immediately disconnected the battery (I have no idea if that was dangerous or not so don't bust me but I I wanted to save the plane) and then I walked away...... grabbed the only liquid i had (Redbull) and waited for the flames....

No flames occurred thankfully, so didn't have to use the redbull...

Opened it up and the speed controller was MELTED!! I mean gone, my nose cone stinks and slightly melted...........

What could have done this? Its been flying perfectly for months, haven't changed anything in it,... i guess over time they deteriorate?

What are peoples thoughts, also would i need to change the motor or would that have been unaffected.

I want to buy a new speed controlled but do I need to do any checks on the rest of the plane, I don't want smoke anymore! Also which one should I buy

So I’m grounded at the moment, I am still new to this so any advise be great.

My plane is the ST Discovery and is all standard haven't touched a thing!

Now sure what parts I need to buy etc…. Help a newbie with a burnt out plane J
